Figure 6.7-22 PWM Pulse Generation in Down Count Type
The PWM generation events may sometimes generated at the same time, as the reason, events
priority between different counter types should be take care are list in Table 6.7.6-1 , Table 6.7.6-2
and Table 6.7.6-3, event priority in up count type, event priority in down count type and event priority
in up-down count type.
